Definitions

  • the invention relates to a transportable barrier system for closing floor and ceiling openings during the construction phase and for creating temporarily required magazine areas in new buildings according to the preamble of claims 1 and 4.
  • openings for the lift shaft and openings for stairs must be made in the walls on each floor. These openings always represent a danger, since with each additional floor a fall into the elevator shaft or through several floors in the stair area becomes more dangerous.
  • Today, such openings are usually closed with bars attached to the walls to the side of the light shaft opening and formwork panels attached in front of them.
  • the construction of such temporary arrangements is time-consuming, since expensive construction timber has to be sawn and, on the other hand, it has to be dismantled again later in a labor-intensive manner.
  • Another The major disadvantage is that with such a temporary casing it cannot be opened briefly or temporarily for access to the lift shaft.
  • Such an arrangement is designed as a single-purpose door and changing the width of the door or the door panel is complex and the production of the door hinges is costly.
  • the ones from the CH 700375 known arrangement can also only be constructed with the fastening means attached to it. Furthermore, this arrangement cannot be used for the creation of temporary magazines on construction sites.
  • One object of the present invention is to create a shut-off system for lift shaft and floor and ceiling openings and for the creation of temporary magazines in new buildings, which can be set up and dismantled on the construction site with little effort.
  • Another object of the invention is to create a barrier system which can remain on site during the entire construction phase and does not hinder the continuation of work such as plastering, painting, carpentry etc. during the construction phase.
  • Another object of the invention is to provide a barrier system which can be adjusted in height while it is in use in order to be able to compensate for coverings such as underlays that have been applied without dismantling.
  • Another object of the invention is to create a barrier system which can be attached to commercially available ceiling supports.
  • the barrier system according to the invention has the advantage that it can be set up and dismantled again without damaging walls and ceilings during the construction period and that it can be set up in such a way that all subsequent work after Creating the partial structures (shell) can remain in place.
  • a particular advantage is that the shut-off system can be used not only to close lift shaft openings, but also all types of openings in floors and ceilings. It can be created by one person, since the fastening element, for example a support, and the individual barrier elements can be brought to the construction site individually and can be joined together individually. In a special embodiment, the shut-off elements can be connected directly to one another without the aid of fastening elements. In this way, floor openings in particular can be provided with a fence.
  • the shut-off system advantageously enables the shut-off element or the shut-off elements to be fastened and removed again at any point without damage to the structure and without tools and using commercially available ceiling supports as fastening elements.
  • the shut-off element or its position can also be adjusted in the vertical direction and adapted to the height of the floor changed during the construction phase. This is achieved by simply moving the hinge parts on the fastening element. A secure hold on the floor and ceiling can be ensured by supporting plates with claws which are arranged at the ends of the fastening element.
  • the shut-off element or the shut-off elements comprise a frame made of vertically and horizontally arranged profiles that are welded to one another or otherwise connected. Bars, grids or plates are inserted between the profiles. These increase the strength of the shut-off element and thus the safety of the shut-off.
  • Two-part hinge arrangements are designed as connecting elements between the fastening element and the shut-off element, which allow easy hanging and unhooking and which, if desired, cause the shut-off element to close automatically through mutually extending contact surfaces that run in a helical manner or are arranged at a 45 ° angle.
  • a second shut-off element is arranged on the first shut-off element, which is laterally displaceable and lockable relative to the first shut-off element.
  • the two shut-off elements are connected to one another by simple slot nuts attached to pegs.
  • the guides for the slot nuts can consist of C-shaped profiles in which the slot nuts are guided. Instead of sliding blocks, rollers or roller bearings can also be used.
  • the two mutually displaceable shut-off elements can be locked and fixed in any desired width.
  • At least two bolt-sliding block connections are arranged in the area of the respective edges that overlap.
  • two horizontally extending tubular frame parts are arranged in pairs on the first shut-off element in the area of the upper edge and the lower edge.
  • Two individual profiles are arranged on the second shut-off element in such a way that, when the two shut-off elements are arranged one above the other, they enter the space between the profiles on the first shut-off element. From the second shut-off element, bolts lead through the profiles arranged in pairs at the first shut-off element and end in end plates that rest on the outside of the profiles that are present in pairs.
  • This embodiment is extremely simple and, above all, absolutely insensitive to dirt with regard to the area of application on the building site, because it is pushed to the side when it is moved by the bolts and consequently no jamming can occur.
  • the barrier elements are arranged on fastening elements such as ceiling supports that define a room. In this way it is possible to open up the defined space between the fastening elements clamped between the floor and the ceiling and to enter.
  • the assembly and dismantling of a magazine area created in this way in a building is tool-free and all elements can be used as often as required.
  • the laborious construction of a magazine area from wooden beams and plates can thus be dispensed with.
  • the hinge parts which are provided with inclined contact surfaces, make it possible, without external interference, that the shut-off elements always return to the closed position if they are not held by human hands or are prevented from pivoting back in some other way. This ensures that openings cannot be left open unattended and that people cannot fall.
  • the locking elements can also be locked to the fastening elements with little effort, e.g. with padlocks, so that access to openings is denied even when the construction site is unattended.
  • the reference number 1 denotes two shut-off elements and the reference number 3 denotes two fastening elements.
  • Each shut-off element 1 comprises a rectangular frame made of two first, vertically arranged Profiles 5 and two second horizontally arranged profiles 7.
  • the first and second profiles 5, 7 are connected to one another at their ends. Additional corner reinforcements such as a footplate 11 or corner angle plates can increase the stability of the shut-off element 1.
  • the two vertical profiles 5 of the shut-off elements 1 can additionally be connected to one another and reinforced by further, ie third, profiles 13. Between the profiles 5, 7 and 13 fillings 15 are attached, which prevent people from passing through and tools from falling down. Bars 17, aligned vertically or horizontally, or a grid or net 19 can be used as fillings 15.
  • Fastening means 21 can be arranged on the first profile 5 located on the left-hand side or on both sides.
  • These include hinge elements 23 which can be releasably and displaceably attached to the fastening element 3 again.
  • the hinge elements 23 are connected directly to the fastening element 3 in a simple embodiment.
  • the hinge elements 23 are connected to the fastening element 3 in a vertically displaceable and lockable manner.
  • the hinge elements 23 are arranged on clamps 25, which clamps 25 wrap around the tubular lower part 27 of the fastening element 3, for example a ceiling support. By loosening or tightening clamping elements such as screws 29, the clamps 25 and the hinge elements 23 attached thereto are displaced vertically.
  • the two clamps 25 can be connected to one another by a rod 31 running parallel to the lower tube 27 in order to enable synchronous displacement (rod shown in broken lines).
  • one of the two tensioning screws 29 can be dispensed with.
  • the two hinge elements 23 can be fastened to a jacket tube which is arranged axially displaceably on the lower tube 27 of the fastening element 3.
  • the cladding tube (not shown) can either be held at the desired height using stopper elements such as bolts that penetrate the lower tube.
  • nuts can also be arranged on a thread arranged on the lower tube, with which the height of the cladding tube and thus the hinges arranged therein can be continuously adjusted.
  • This embodiment has the advantage that the height of the shut-off elements 1 can be adjusted at any time by one person and without dismantling the fastening elements 3.
  • the fastening element 3 comprises a second upper tube 33 which can telescopically engage in the lower tube 27.
  • the upper tube 33 can adjusted by an adjusting device 35, which is not described in detail, and thus the height of the fastening element can be determined.
  • the fastening element 3 can be clamped between the floor and the ceiling of a room.
  • Support plates 37 on which pointed prongs 39 are formed, can be attached to the ends of the lower tube 27 and the upper tube 33. Sockets 39 can be arranged on the support plates 37, which, for example, remain on the floor as lost elements in the coatings after the casting of coatings.
  • handles 51 are preferably arranged, on which, when the lift opening is closed, the pulled shut-off element 1 comes into abutment and, if necessary, can be fastened or locked there with a padlock on the second fastening element.
  • shut-off element 1 At an angle of about 45 ° or helically formed contact surfaces 53 between the upper and lower hinge parts cause the shut-off element 1 to always rotate from the open position to the closed position and thus safely cover the opening cross-section of lift chess openings.
  • shut-off elements 1 are connected to one another in a transversely displaceable manner by guide profiles 39 and sliding blocks 41 or rollers guided therein.
  • the guide profiles 39 can be attached to the second, horizontally lying profiles 7 or additionally also to the profile 13 of the shut-off element 1, or they themselves form the second profiles 7, which connect the two vertical first profiles 5 to one another.
  • FIG 4 is the position of the shut-off elements 1 in the closed position according to Figure 1 shown in section. It can be seen that the shut-off elements 1 partially overlap in the central area or at their ends and are guided there in parallel by a guide arrangement 55. On the right-hand side it can be seen that the pulled shut-off element 1 rests on the handle 51 with the fastening element 3.
  • additional hinges can be arranged on the vertical profiles 5 of the barrier elements, with two upwardly directed hinge pins being attached to one side of the barrier element and on the Profile on the opposite side, sleeves are attached at the appropriate height, the inner diameter of which corresponds to the diameter of the pins on the opposite side.
  • the horizontal second profile 7 has a C-shaped cross section, the laterally running slot 7 'of which is directed towards the second shut-off element.
  • the second profile 7 consists of a rectangular profile. The latter is penetrated by a bolt 43, at the right end of which a slot nut 41 is attached. On the left end there is a nut 57, preferably a self-locking nut.
  • a nut 57 On the left end there is a nut 57, preferably a self-locking nut.
  • three slot nuts 41 with bolts 43 are arranged on the second profile 7 on the upper edge of the shut-off element and the same number on the lower, second profile 7.
  • the sliding block 41 can as in Figure 6 be designed as a flat disk or flat rectangular plate.
  • a T-slot nut 41 can be provided with a T-shaped cross-section, which engages wedge-like in the slot 7 'on the profile 7 and partially completely fills the rest of the cross-section of the second profile 7.
  • the sliding block 41 slides along the edges on the slot 7 ', and not the bolt 43 as in FIG Figure 6 shown.
  • a ball bearing or a rotatably mounted disc which is guided in the C-shaped guide profile 39, can also be placed on the end of the bolt 43.
  • two bolts 43 with slot nuts 41 are arranged on the overlapping areas of the guide profiles 39 (when the shut-off elements 1 are extended) in order to prevent the shut-off elements 1 from tilting when the shut-off elements 1 are pulled out or pushed together.
  • locking screws 45 can be provided above and / or below or on a middle profile 13 to lock the two interacting shut-off elements 1.
  • the bolt 43 which carries the sliding block 41, can also be axially displaceable and thus cause a locking between the two shut-off elements 1.
  • FIGS. 7 to 10 show a further embodiment of a guide arrangement 55.
  • one of the two shut-off elements 1 is the upper second Profile 7 formed from two profiles with a mutual spacing.
  • the three screws 59 for example, can mesh with the corresponding threaded bores in the sliding bearing element 63 or be held there by means of screws.
  • the sliding bearing element 63 consequently bears the load of the displaceable shut-off element and transfers it to the lower of the two parallel profiles 7 arranged at a distance.
  • the sliding bearing element 63 consists of a plastic material that slides well.
  • the shut-off element 1 can consequently be arranged as a pivotable door in front of a lift shaft opening.
  • the fastening element 3 is initially aligned and clamped exactly vertically laterally or within the opening between the floor and ceiling of the building.
  • a second fastening element 3 is clamped on the right-hand side of the shut-off element 3 in the same way between the floor and the ceiling, and the door can now be hung.
  • the locking part 47 protruding from the fastening element 3 serves, on the one hand, to secure the shut-off element 1 to a stop part 49 correspondingly arranged on the shut-off element 1 on the right-hand side positioned in the closed position.
  • a lock can be attached to the locking part 47 and the stop part 49, which creates a lockable connection between the two parts.
  • the locking part 47 is arranged on the fastening element 3 so as to be vertically displaceable, for example on the rod 31 - if present - or on a clamp so that the locking element 1 can be locked in any vertical position.
  • the displaceability of the hinge part 3 23 on the fastening element 3 serves to lift the shut-off element 1, for example, when a covering such as a cover or a paving is applied to the raw surface of the building floor.
  • a toothed rail 65 similar to that used in rack railways, can be fastened to the fastening element 3.
  • This rail 65 makes it possible to insert the clamp 25 or the shaft of the screw 29 on the clamp 25 between two teeth of the toothed rod and thus to set the height not by frictional engagement, but by positive locking of the connection of the hinges on the fastening element 3.
  • shut-off element 1 it can be used as a temporarily buildable closing wall to form a magazine.
  • shut-off elements 1 and the associated fastening elements 3 are arranged between the floor and ceiling, for example a basement, of the building and the spaces are closed by the shut-off elements. In this way, the blocked area is accessible from all sides, in that the corresponding blocking element 1 can be opened or closed in each case.
